Important medical disclaimer
Educational tools only — not medical care
Migraine Trail is not a healthcare provider, medical service, or medical device. These tools use information you enter and simplified educational rules. They may be incomplete or wrong and cannot examine you.
- Results do not diagnose, rule out, confirm, or predict any disease, headache type, trigger, emergency, or personal medical risk.
- Do not start, stop, combine, delay, or change a medicine or treatment—and do not delay professional care—because of a result.
- Labels such as “pattern,” “alignment,” “score,” “threshold,” “risk,” or “urgency” are educational summaries, not clinical findings or probabilities.
Discuss symptoms and decisions with a licensed healthcare professional who knows your history. For a child, involve a parent or guardian and an appropriate pediatric clinician.
If symptoms may be an emergency, stop using this site. Call your local emergency number or seek emergency care now. Never wait for or rely on a tool result.

MIDAS Migraine Disability Score Calculator
Measure how headaches affected your work, home responsibilities, and activities during the last three months.
Answer for all headaches during the last 3 months, not just the most severe attacks. Enter 0 when a question does not apply. Questions 1–5 make up the score; A and B add context.
MIDAS score ranges
The MIDAS score is the sum of questions 1–5. Questions A and B do not change the grade. A disability score is not the same as a diagnosis, headache-day classification, or legal determination of disability.
Frequently asked questions
What is a MIDAS score?
It is a three-month measure of headache-related disability across paid work or education, household work, and family, social, or leisure activities.
What if I do not work or attend school?
Enter 0 for the two work or school questions. Household and social activity questions still contribute to the score.
Does MIDAS diagnose migraine?
No. MIDAS measures the effect of headaches on daily function. It cannot identify the headache type or replace a medical assessment.
